The operation principle of the test-bed for the detection anti-rejection attaching means performance of pipeline that the present embodiment is provided：
The anti-rejection attaching means that need to be tested is arranged on base station, and jump bit lifts the height to setting by jump bit elevating mechanism
Spend H1.Meanwhile, balancing weight is placed according to calculating in counter weight device, and after being lifted by hydraulic lifting apparatus, with passing through girder steel
Boatswain chair and the disconnected pin of hammer are suspended on auxiliary frame, then release hydraulic lifting apparatus.Disconnected pin hammer is hammered elevating mechanism into shape by disconnected pin and carried
It is raised to setting height H2.The hoisting depth H1 of jump bit should hammer hoisting depth H2 and jump bit relieving mechanism and disconnected pin hammer into shape with disconnected pin
The actuation time of relieving mechanism mutually coordinates, while the jump bit is impacted anti-rejection attaching means, and the disconnected pin of hammer is disconnected by rapid hammer, will match somebody with somebody
The gravity put is reset while being transferred on anti-rejection attaching means.
In addition, as shown in figure 3, making the anti-rejection attaching means (18) that U-bend song is made with strip material, restrained pipeline is placed in
U-shaped inner chamber.Moved downward during pipeline whipping, impact U-bend, the stretching plastic deformation through strip material absorbs impact energy.
This test-bed simulates the whipping of pipeline using jump bit (5) free falling.It is required that when impact velocity is 10m/s, jump bit
Height of drop H1 should be not less than 5m；It is required that when impact velocity is 20m/s, the height of drop H of jump bit should be not less than 20m.Impact
The quality of hammer should be slightly bigger than impact kinetic energy/height of the fall H1, because the potential variation in jump bit whereabouts has sub-fraction and disappeared
Consumption is in the deformation of jump bit etc..
In order to simulate the whipping of pipeline, jump bit end cambered surface (7) and provide the girder steel (12) of continuing load with it is anti-rejection about
The lower camber side (20) that bundle (18) is in contact should be identical with the excircle dimension of restrained pipeline.
In order to ensure that jump bit falls to orienting, jump bit both sides are provided with leading truck.Meanwhile, in order to ensure that impact energy is direct
Act on anti-rejection attaching means, the girder steel center of simulation continuing load will set avoidance hole (19).
In order to simulate medium injection sustained load during pipeline breaking, using being placed in the anti-rejection attaching means inner chamber girder steel of pipeline
(12) two ends suspended counterweight device (another scheme, hang constant hanger) simulates sustained load.Hang on girder steel (12)
On counterweight frame (13-1,13-2) in place balancing weight (14-1,14-2).Counter weight device is completed after counterweight, by with refitting
Lifting hydraulic cylinder (8-1,8-2,8-3,8-4) lifting counter weight device is put, leads to the girder steel boatswain chair (11-1) (11-2) of connection girder steel
Cross load-bearing otic placode (9-1) (9-2) (9-3) (9- that the disconnected pin (10-1) (10-2) of hammer is connected on auxiliary frame (15-1) (15-2)
4).Complete after girder steel boatswain chair and the connection of load-bearing journal stirrup, release hydraulic lifting apparatus connection.
The top of the disconnected pin of hammer sets the pin hammer (3-1,3-2) that breaks, and the pin that breaks is hammered into shape to arrive by the disconnected pin lifting device (2-1,2-2) of hammer and needed
The height wanted.In order to just hit hammer disconnected pin when ensureing that disconnected pin hammer falls, in disconnected pin hammer both sides provided with disconnected pin hammer leading truck.In order to
Ensure disconnected pin (10-1) (10-2) plane of disruption of hammer will not jam girder steel boatswain chair fall rapidly from load-bearing otic placode, the disconnected pin of hammer is preferably used
Fragile material is manufactured, and sets hammer fault trough (22-1) (22-2) and (22-3) (22-4) in the section for requiring to cut.
Counter weight device is collided after constantly, preventing anti-rejection attaching means (18) to be thrust using counter weight device offer continuing load
Auxiliary frame or ground, thus add buffer spring (16-1) (16-2) (16-3) (16-4).
When providing continuing load using spring constant hanger (24-1) (24-2), the two groups of springs in left and right are accurately adjusted
The output load of formula constant hanger (24-1) (24-2) is equal, and slewing frame (26-1) (26-2) is from stroke end to stroke
The not constant force degree of output load is as far as possible small between point.
